Fortinet FortiGate's customer support is generally positive but varies in responsiveness and expertise, influenced by region and support tier.
Sentiment score
6.3
Microsoft Exchange Online Protection customer service is praised for availability but criticized for inconsistent response quality and speed.
Sentiment score
7.2
WatchGuard Firebox support is praised for quick, knowledgeable service, though some delays occur in different time zones.
They offer very accurate solutions.
The quick resolution of issues with Fortinet FortiGate is due to the support of the company and the fact that the equipment is easy to work with.
I would rate the technical support for Fortinet FortiGate a ten out of ten.
Microsoft offers excellent 24/7 support.
My team is able to get the help they need when necessary.
On a scale of one to 10, I would rate the technical support of the WatchGuard Firebox a 10.
The technical support is good.
 

Scalability Issues

Sentiment score
6.9
Fortinet FortiGate effectively supports scalable deployments, offering adaptability despite potential hardware limits and integration and licensing concerns.
Sentiment score
7.8
Microsoft Exchange Online Protection offers scalable security solutions despite some limitations, appreciated for ease of use and high satisfaction.
Sentiment score
8.1
WatchGuard Firebox is scalable for various needs, with upgrading options, though choices affect its scalability and performance.
They scale up really well from smaller models like the FortiGate 40 and 50 to bigger sites with the FortiGate 100 for more throughput - up to enterprise datacenters.
The variation comes in terms of the interfaces and throughputs, but from a security perspective, you get the same benefit, irrespective of whether you have an entry-level unit or an enterprise.
We determine sizing based on multiple factors: number of users, available links, traffic types, server count, services in use, and whether services will be published.
If we're going for more concurrent users, we need to change the entire box.
I find the WatchGuard Firebox scalable, as it's easy to change configurations from this product to another one.
 

Stability Issues

Sentiment score
7.4
FortiGate is praised for stability and performance, with minor challenges managed by updates, proper sizing, and support.
Sentiment score
7.7
Microsoft Exchange Online Protection is reliable, scoring high in stability, with issues mainly from configuration and occasional interface changes.
Sentiment score
8.6
WatchGuard Firebox is highly stable and reliable, with few issues, frequent updates, and high user satisfaction ratings.
We're experiencing 99.999% availability consistently.
I would rate the stability of Fortinet FortiGate a ten out of ten.
Currently, we are experiencing a general outage of one of the main internet service providers of the Dominican Republic, and we have not been impacted in our operations because with SD-WAN, we have another internet service provider and we are working with the second WAN connection without any disruption.
 

Room For Improvement

Fortinet FortiGate struggles with integration, user complexity, support inefficiencies, high costs, and feature performance, needing improved documentation and security.
Microsoft Exchange Online Protection needs better integration, enhanced security features, improved user experience, and competitive pricing for increased effectiveness.
WatchGuard Firebox needs a modern interface, better integration, enhanced features, and competitive pricing to improve user experience and marketability.
Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
The constant daily revisions necessitate meticulous identification of the relevant documents to prevent the use of outdated information that could jeopardize our environment.
While Fortinet claims to offer a comprehensive network solution, it falls short in addressing computer application issues, particularly server security.
Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous.
The cost for renewal after three years is 75% of the hardware cost, which is a significant problem.
When implementing a rule using a group of IPs, it is not possible to do that directly.
The WatchGuard Firebox has certain features, but the challenge is that we have some clients who don't have a network or are only mobile users, which leads us to think the future is in SASE products, not in the WatchGuard Firebox.
 

Setup Cost

Fortinet FortiGate offers competitive, cost-effective pricing, appealing to small-medium businesses with flexible licensing and valued security solutions.
Microsoft Exchange Online Protection offers tiered pricing, seen as high but justified by robust security and scalability features.
WatchGuard Firebox offers cost-effective pricing, especially for multi-year plans, with discounts and value for budget-conscious enterprises.
FortiGate is priced lower than Palo Alto.
Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us.
It is about 20% cheaper.
The pricing is reasonable.
Microsoft Exchange is more expensive compared to other services like Gmail.
When we tried to renew the Palo Alto license, the cost was beyond any reasonable range.
It's expensive us here.
I have faced challenges with the WatchGuard Firebox regarding price since we work with customers who use the Stormshield product, which is less expensive and French-made.
 

Valuable Features

Fortinet FortiGate is user-friendly, cost-effective, and offers high-performance comprehensive security with advanced threat protection features.
Microsoft Exchange Online Protection offers scalable, user-friendly security features with AI-enhanced threat management and seamless integration with Microsoft tools.
WatchGuard Firebox offers user-friendly setup, robust security, excellent tech support, and scalable performance with comprehensive management features.
In terms of security, we have not experienced any security flaws or loopholes, and it has proven to be quite stable.
FortiGate has helped reduce the risk of cyberattacks that might disrupt our client's production.
These features help reduce our downtime, manage the ISPs, and deploy SLAs for all the website traffic.
The security features provided by Microsoft are robust.
It offers more features and better security, making it the best option for corporate environments.
In the last three years, has resulted in no antivirus problems.
The Firebox offers valuable features such as network security, URL filtering, UTM features, intrusion prevention and detection, and authentication.
Basically, we have received a good return on investment.
I utilize AI within the WatchGuard Firebox, as we use the interconnection with threat syncs, and AI is implemented.

Vasu Gala - PeerSpot reviewer
A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Retrieves data from quarantines and easy to read logs with robust security features
Some of the searchability when looking for specifics in Exchange logs is tedious. Although eventually the information is located, it can be difficult if detailed information is lacking. Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous. Simplifying interfaces would also be appreciated.
Rajesh  Makwana - PeerSpot reviewer
Efficient bandwidth management and secure network access with a strong firewall
The primary use case of the Firebox mainly revolves around bandwidth management, unnecessary web blocking, application control, and protection against brute force attacks. It is also implemented for load balancing, SD-WAN, and branch-to-branch connectivity from one location to another. We also use…
